Spring applications A spring has to meet many challenging requirements. First of all, it must provide the required spring force. It also has to function reliably during a long service life, even if its working environment is corrosive or demanding in other ways. Furthermore, it is an advantage if the spring is easy to manufacture. Therefore, formability of the material is very important. Sandvik Materials Technology offers a wide range of strip steel in both stainless and carbon steel grades for the manufacture of coiled and formed springs. Austenitic and duplex stainless steels Our product program comprises many different grades, performance capabilities and dimensions for all types of demanding applications with different requirements on strength, relaxation resistance, fatigue strength, corrosion resistance and ductility. We specialize in the production of extremely thin strip (down to 0.015 mm, 0.0006 in.) with high strength (up to 2050 MPa, 297 ksi) and very close thickness tolerances (down to ±0.0015 mm, 0.00004 in.). For spring manufacturing involving severe forming and/or requirements with a low springback, we can deliver strip in a relatively soft condition to assist forming. A simple tempering heat treatment increases strength by 50-800 MPa (7-116 ksi) depending on grade and the initial tensile strength. Martensitic stainless chromium steel and carbon steels Hardened and tempered stainless chromium steel is used mainly for springs for which a very high degree of flatness is required. For purposes where resistance to corrosion is not important, carbon steel strip in the hardened and tempered condition may also be an alternative. To further improve fatigue life, we offer strip with rounded edges. Sandvik also manufactures stainless steel for springs in the form of round and flat wire.

Sandvik Bioline 316LVM is specially tailored for implant applications. The vaccum re-melting process together with strict chemical control produces a high purity product with good mechanical properties and resistance to corrosion. Austenitic and duplex stainless steels Our modern and technically advanced cold rolling mills, with automatic thickness controls, enable us to manufacture cold rolled strip that meets very tight thickness tolerances. In addition to our standard austenitic steels, we have a wide range of special grades, each with specific properties, e.g. non-magnetic, very high corrosion resistance or excellent formability. Examples of applications for thin precision strip include parts in mobile phones or in printers, gaskets for electromagnetic shielding and expansion bellows in thermostats. Martensitic stainless chromium steels The proportion of carbon to chromium in the steel is carefully controlled to give the steel good hardening and tempering properties. Sandvik Chromflex is a family of martensitic, stainless chromium strip steels with a unique combination of very good properties; tensile strength, shape, resistance to wear and fatigue strength. An example of end use is sealing strip in pneumatic cylinders. It is also suitable for photochemical machining, laser and water jet cutting of components for the electrical and medical industries.

Industrial blade applications Sandvik s leading metallurgy enables us to produce strip steel with optimum and consistent properties. The materials, which we produce for blades in the printing and food processing industries, have been tailored to achieve the highest precision and best possible performance. Cold rolling provides the basis Our modern cold rolling mills produce strip steel with close thickness tolerances and excellent straightness. A perfect shape is produced in the strip in order to achieve the desired straightness. The hardening process is the key In the hardening and tempering process the final microstructure, mechanical properties and flatness of the strip products are set. Through in-line polishing the surface execution is obtained as well. Blades for customers requirements Straightness, wear resistance, microstructure and strength have to meet very high standards as a prerequisite for smooth, problem free manufacturing and perfect processing. The edge execution is of utmost importance and we can tailor a variety of edges to fit our customers demands. To the printing industry Sandvik offers a wide product portfolio for doctor blades that matches the requirements of the segment.

Surfaces Surface finish Sandvik strip steel can be delivered in several different surface finishes. To describe a surface appearance correctly, one has to indicate both its appearance and its roughness. Surface appearance In the table, surface appearance is defined in terms of brightness and color. Stainless steels are not usually color tempered and are, therefore, not delivered in codes 6 and 7. Surface roughness Surface roughness is measured with a special trailing-stylus instrument. The relevant terminology and measuring methods can be found in EN ISO 4287 and EN ISO 4288. Surface roughness Class Class limit Class mean Ra, µm (µin.) Ra µm (µin.)

The choice of edge finish depends on the application; however, the availability of finishes is dependent on steel grade, size and tolerance. Here only standard profiles are shown, but other finishes are also available, e.g bevelled edge. a) Mill edge Untreated edge, generally with a somewhat uneven contour. No width tolerance is normally stated. c) Deburred edge Slit edge from which the burr has been removed. d) Square edge Sharp cornered square edge. Obtainable in widths up to 150 mm. Some hardened grades can be supplied with this edge in widths up to 430 mm. e) Square edge with rounded corners Widths up to 150 mm. f) Round edge Edge completely rounded. Obtainable in widths up to 150 mm. b) Slit edge Edge with the shearing burr left on. This edge is obtained by slitting with a circular shear. 8

Waviness Coil set Cross bow Shape To ensure the dimensional accuracy of products, our cold rolling mills are equipped with automatic gauge control and roll gap symmetry systems. Any deviations in shape characteristics are measured to guarantee the dimensions of the products delivered. The important characteristics for strip products are typically thickness, flatness and straightness. Deviations from flatness could be in the form of waviness (like edge waves or internal buckles), coil set and cross bow. Standards for deviations in coil set and cross bow according to different tolerance classes are given in the tables.

Subsequent hardening and tempering makes the steel hard, tough, resistant to wear and suitable for use as springs and other high strength applications. Martensitic stainless chromium steels These steels have excellent properties for forming and grinding sharp edges and, after hardening and tempering, also good resistance to corrosion. Sandvik 6C27, 7C27Mo2, 12C27 and 13C26 in the hardened and tempered versions are supplied under the trade name Sandvik Chromflex. Their special characteristics include good resistance to wear, high fatigue strength and very good flatness, as well as uniform mechanical properties along and across the rolling direction (isotropic properties). Austenitic stainless steels These steels have superior qualities in respect of resistance to corrosion combined with very good spring properties, low relaxation and high fatigue strength. The strength in these grades is achieved by cold rolling, which makes them available in a wide range of dimensions and mechanical properties. A further increase in strength can be obtained by a simple heat treatment in the temperature range 350-480 C depending on grade. Duplex stainless steels (austenitic-ferritic) The modern duplex steels have excellent corrosion properties. They are not as sensitive to stress corrosion cracking as austenitic steels. Thermal expansion is lower than for austenitic steels, which can offer design advantages in certain cases. 10

Size tolerances In the standard finish, the tolerance is symmetrical, half above and half below the nominal size. Other tolerance dispositions can be discussed. The normal width tolerance class is B1, but slit strip can be supplied with B2 or B3 tolerances on request. Closer tolerances require special edge treatment. For austenitic and duplex stainless steels other width tolerances are applicable according to EN 10258, see brochure S-3411.
